Setting up a domain and HTTPS

For full internet Betula experience, you will need to set up a domain and, preferably, HTTPS. If you are just using Betula locally, do not bother, unless you want to.

Setting up a domain

Domains cost money. Pick a good registrar and buy your domain. It doesn't really matter which one you buy, they work basically the same. Some good registrars are Gandi, Dynadot, Beget (recommended for Russian users). Avoid GoDaddy, it has a very poor user experience and customer support.

Usually, Betula is served with a subdomain. For example, if you have bought, should lead to your personal site, and should lead to your Betula. links. subdomains are recommended, most betulists use them, some use betula. though. You can serve Betula on a top-level domain too, of course.

In your domain registrar control panel, find DNS management. DNS is the database used for domain name resolution. For your chosen domain, add a A record and write your server's IP as its value. Save. DNS might take a while to update.

Now, your Betula is available on http://yourdomain:port. It's not good enough.

Setting up HTTPS (and port redirection)

HTTPS is used for secure page loading in the Web. You should use it for security. Other Fediverse instances will ignore your server if it doesn't have HTTPS. Usually, HTTPS certificates cost money. Luckily, Let's Encrypt offers free certificates for everyone; we're going to use them.

Reverse proxy is a web application that forwards requests and modifies them in a specific manner. Betula relies on reverse proxies for domain and HTTPS support.

We provide guides for nginx and Caddy below. You can use any other reverse proxy, if you want.


Nginx is a popular web server application. It can be used as a reverse proxy. Your server might already have it installed.

After installing nginx, edit /etc/nginx/nginx.conf. In http section, create a new server section for your Betula:

# ...

http {
	# ...

	# Very recommended to have the next line, it makes loading faster for users.
	gzip on;

	server {
		# Change with your domain.

		location / {
			# Change with your port, if you don't use 1738.
			# Required for Fediverse.
			proxy_set_header Host $host;

	# ...

For HTTPS support, we recommend using certbot. It gives you free HTTPS certificates and updates nginx config for you.

Run Certbot. It sets up certificates and HTTPS to HTTP redirections. If you want to disable HTTPS to HTTP redirections, edit the nginx configuration file.


Unlike other web servers, Caddy offers built-in HTTPS management.

The guide is yet to be written. If you had a good experience setting up Betula with Caddy, please tell us.


In your Betula settings, write down your domain. Doing so ensures RSS feeds, bookmarklet and federation work correctly. Now, you are ready for the internet.
